VECTORPIE/VECTORCHORD

typedef struct tagVECTORPIE
{
   VECTOROBJECT Object;
   VECTORPOINT Point;
   VECTORPEN Pen;

The VECTORPIE structure holds information about a vector arc object.

The VECTORCHORD structure holds information about a vector chord object.

Member	Description
Object	Abstract object.
Point	A VECTORPOINT structure that contains the vertex of a vector pie object, about which the pie section or chord sweeps.
Pen	VECTORPEN structure that contains information about the pen to use when drawing the vector pie or vector chord object.
Brush	VECTORBRUSH structure that contains information about the brush to use when drawing the vector pie or vector chord object.
Radius	Length of the radius of the vector pie or vector chord object. This value is in logical units.
StartAngle	The angle at which to begin the vector pie or vector chord. Values should be between 0 and 360 degrees. Values less than 0 and greater than 360 will be modified internally.
SweepAngle	The angle through which to sweep the vector pie or vector chord. Values should be between –360 and +360 degrees. Positive angles will be drawn in a counter-clockwise direction from StartAngle. Negative angles will be drawn in a clockwise direction.

Comments

nSize of the Object member must be the sizeof this structure.

nType of the Object member must be VECTOR_PIE or VECTOR_CHORD.

pVECTORPIE is a pointer to a VECTORPIE structure.

pVECTORCHORD is a pointer to a VECTORCHORD structure.

The diagram below gives a graphical representation of of the Point, Radius, StartAngle and SweepAngle parameters.
